Guadalupe Junco Junco insularis

Small, sparrow-like bird found only on Mexico’s Guadalupe Island, located in the Pacific Ocean 160 miles west of Baja California. It has a gray hood, dark face, tawny flanks, pale bill, and white outer tail feathers that flash conspicuously in flight. No other similar bird is found on the island. Found in a wide variety of habitats as long as native vegetation remains. Song is a short burst of sweet chips and trills, repeated every few seconds. Highly endangered due to habitat loss and introduced predators.
